i figure at some point someone is going to make a water cooled led heatsink. they are somewhat common for computers and an led heatsink is essentially the same construction as one for a cpu. something like this. if your specific problem is that you can't get air exchanges to cool the stock heatsink, this would move the heat transfer part to a remote location.

I am surprised that marble panels in Beinecke Library at Yale are 1 1/4-inch thick. Seems really thick for marble to allow any translucency. Is it onyx marble? I think at those thicknesses stone needs to be chemically treated/soaked and then waxed multiple time for the transparency to show up...

It's not the thickness of the marble that allows translucency, it's the intensity of the New Haven sun that makes them glow.
